About This Set
One rule settles every question in this set: favourable outcomes over total outcomes, a complement, odds turned into a probability, or two independent chances multiplied. The mistakes that cost marks here are small ones: 1 taken as a prime, (3, 6) and (6, 3) counted as one outcome, a coin and a die given outcomes when there are , and the red face cards counted twice in a red card or a face card. Take about 20 minutes. With 21 or more right, your counting is reliable enough for Practice Set 2.
